| Portfolio | Reported | Closed | Paid | Case | Expected Claims | Expected Loss Ratio |
|---|---|---|---|---|---|---|
| Motor Physical Damage | 120 | 72 | 245000 | 98000 | 150 | 58% |
| Property Small Commercial | 40 | 21 | 164000 | 91000 | 52 | 63% |

This calculator combines three reserve views into one selected ultimate estimate. The first view is paid plus case. The second is expected loss ratio multiplied by earned premium. The third is expected claim count multiplied by selected severity.
1. Selected Severity
Selected Severity = Average Paid per Closed Claim
2. Weighted Ultimate
Weighted Ultimate = (0.45 × (Paid + Case)) + (0.30 × (Earned Premium × Expected Loss Ratio)) + (0.25 × (Expected Claims × Selected Severity))
3. Gross Selected Ultimate
Gross Selected Ultimate = Weighted Ultimate × Tail Factor
4. Inflated Ultimate
Inflated Ultimate = Gross Selected Ultimate × (1 + Inflation Rate)
5. Gross Reserve Need
Gross Reserve Need = Inflated Ultimate − Paid to Date
6. Net Reserve Before LAE
Net Reserve Before LAE = Gross Reserve Need − Expected Recoveries
7. Final Indicated Reserve
Final Reserve = Net Reserve Before LAE + LAE + Confidence Margin
This structure is practical for finance teams. It creates a reserve indication from current claim data, premium-based expectations, and future uncertainty adjustments.
Claim reserves affect reported earnings, capital use, pricing feedback, and management confidence. A structured estimate helps teams compare current case reserves with a broader view of expected ultimate cost. Finance managers can test inflation, recoveries, and margins quickly. This supports planning discussions without replacing detailed actuarial work.
The model is useful when month-end reporting needs a practical reserve check. Paid and case values show current development. Expected claim counts and severity provide exposure to claims not fully developed. The premium and loss ratio view adds a portfolio benchmark. The weighted approach reduces dependence on one method alone.
Tail factor is important for long settlement patterns. Inflation helps reflect changing repair, medical, legal, or service costs. Recovery assumptions reduce net reserve where subrogation, salvage, or reimbursements are expected. LAE adds expected handling cost. A confidence margin creates a management cushion for uncertainty.
Use the output to compare reserve need against booked case balances, estimate IBNR, and communicate a consistent narrative across underwriting, finance, and claims teams.
A claim reserve estimate is the expected amount needed to settle reported and unreported claims, including future development and related handling costs.
IBNR means incurred but not reported. It also often covers claims reported but not yet fully developed.
A tail factor extends observed loss development into later periods. It helps when claims settle slowly or continue to grow after current reporting dates.
Inflation adjusts expected future settlement costs. This matters when repair, labor, legal, or medical expenses are increasing.
LAE means loss adjustment expense. It covers claim handling, investigation, legal support, and related settlement administration costs.
Yes. It is designed as a practical estimate tool. It helps finance teams review reserve adequacy before deeper actuarial analysis.
No. It is a management calculator. It supports review, planning, and sensitivity testing, but it does not replace formal actuarial methods.
Paid losses, case reserves, expected loss ratio, severity, tail factor, and inflation usually have the strongest effect on the final reserve.
